Amateur astronomer, discoverer of 82 variable stars, 10 planetary nebulae candidates (+5 co-dis.), 3 supernovae, 4 wide binaries (pairs of stars), 3 novae in M31; 4 transients (possible supernovae) and 11 asteroids.Author and co-author of scientific papers
On 2025-10-02 I observed interstellar comet 3I/ATLAS (before passing Mars) at remote 0.25-m f/3.8 reflector T75 iTelescope.Net, Chile. 1st photo is in color.
I also observed it on September 27th - Autumn Astronomy Day.

On 2025-10-02, remotely at the 2-m Liverpool Telescope, I confirmed minorplanetcenter.net/mpec/K25/K25... near-Earth asteroid 2025 TF = C15KM95 which had previously approached at a distance of several hundred kilometers from the Earth's surface. Image: stacked 16x60 sec.

On 2025-09-13 I confirmed new bright comet SWAN25B remotely at iTelescope.Net T59 (0.51-m f/6.8
reflector) in Australia.
I measured: coma +8.9 mag. 2 arcmin., tail=18 arcmin, PA=112°
Images: 3x10s. (RGB), 60s. (Lum)

Approximate (all data is different):
Images 1-4, 9 and 11 are the results of stacking (in RegiStax 5.1) ≈ 300 frames from 640x480 videos, shutter speeds 1/500...1/640 sec., ISO 100...400.
For the rest of the photos: exposures from 1 to 3 sec., ISO=400...1600, some frames are stacked 3-5 images each.
